Lately, upon responding to any meeting invite, I see the communication arrows for a moment, and then I get the red 'X' as if the response was not sent. I have found that the organizer is receiving a response from me, but on my end it looks as if I need to resend the response. Anyone got any ideas how to prevent the failed send? (Besides the obvious choice not to respond to the meeting reques - for all you jokers out there )
